I'm a technical writer by trade and have been doing so for over 12 years now. I've written four modules for the RPGA's Living Greyhawk campaign (Bandit Kingdoms region), averaging one a year until the switch to LFR in 2008. I've been playing RPGs since 1977, starting with the first AD&D box set (not Basic D&D, before that).
I have a long-standing campaign run using the Fantasy Hero rules from HERO Games that has been running since the late 80's. This campaign is on indefinite hiatus while I run a Champions game, The Bold and The Determined.
With a second, slightly different group, I ran AEG's World's Largest Dungeon, finishing after two years of play. I am now running them in a campaign (Naze Valley Rangers) using the Pathfinder RPG.
